Patent CA-2277512-A1 (CA)
Inventor: DOMPAS JOHN
IPC: B22D11/06
Filed: 1999-07-16
Abstract: Edge-dam blocks assembled with their upstream faces in keyed mating interengagement with downstream faces of adjacent blocks form an endless edge dam revolvable in a preselected path for defining a boundary of a moving-mold casting region. The edge dam keeps molten metal in the casting region. Upstream and downstream faces of adjacent blocks have mutually complementary shapes for minimizing intrusion of molten metal between abutting blocks. Keying engagement between abutting blocks prevents relative translational slippage of blocks toward or away from molten metal. An abuttable face on each block has at least one protrusion such as an integral elongated key extending perpendicularly to a casting belt associated with the casting region, or the protrusion includes two round pins having projecting tapered ends. Another abuttable face has a recess such as a keyway for snugly receiving a key on an adjacent block or has two tapered recesses for snugly receiving two tapered projections of an adjacent block.      External edges and root fillets of keys (and shoulders and root fillets of keyways) are radiused with radii in a range between about 1.2 and about 3 millimeters. Blocks' lower surfaces are shown having slots for receiving a tension member. A key's lower end may be undercut near the slot for relieving stress concentration. A pair of parallel undercut fillets are shown extending along opposite sides of a key. They have a radius in a range from about 3 to about 5 millimeters.

Title: Automated teller machine passbook transport mechanism
Inventor: MEYER JERRY L
IPC: B41J15/04
Filed: 1995-06-02
Abstract: A passbook transport and handling apparatus (10) for transporting a passbook between a customer using an automated banking machine and a printer (12) located inside the banking machine includes first belt flights (32) movable on first pulleys (22). The transport further includes second belt flights (34) movable on second pulleys (28). The second belt flights are disposed traversely intermediate of the first belt flights so that a passbook carried therein between is engaged firmly but with limited slippage. The passbook is guided through the transport by a first fixed edge guide (44). A second edge guide (46) is mounted on a spring (48) so as to bias the passbook into alignment as it passes through the transport. A gate member (72) is movable between positions blocking or admitting a passbook to the transport.  Movement of the gate member as well as the belt flights is under control of a processor. Sensors (110), (114), (118) and (124) are operatively connected to and are controlled by the processor and prevent the admission and passage of improperly sized passbooks by the transport.

Title: Sewing ring having increased annular coaptation
Inventor: STARR ALBERT
IPC: A61F2/24
Filed: 1998-07-16
Abstract: A sewing ring for implantation of prosthetic heart valves has a compliant ring member made of a plurality of cells. The ring member may be silicon rubber and the cells defined within outer walls and inner ribs.  A biocompatible fabric covering surrounds at least an outer portion of the ring member, and the assembly mounts to a mechanical or tissue-type prosthetic heart valve. The ring member has a radial dimension and cross-sectional area sufficient to ensure a large coaptation area between the sewing ring and the annulus tissue so as to enable adequate attachment of the valve without load distributing devices such as pledgets. A version of the sewing ring for attachment to the mitral annulus includes a curved coaptation edge, while another embodiment for attachment to the aortic annulus has a tapered outer edge with increased radial and axial dimensions. The sewing ring eliminates the need for pledgets, reduces the number of sutures required, lessens the potential for decubitous ulceration, and provides a better seal against perivalvular leakage. Moreover, the aortic valve sewing ring is sufficiently flexible and large to be able to be placed infra- or supra-annularly, as the surgeons deem best for the patient.

Title: Medical infusion device with a source of controlled compliance
Inventor: GRAY JOHN F
IPC: A61K9/22
Filed: 1999-06-18
Abstract: Embodiments of medical infusion pumps are provided that include structural elements for providing sources of compliance within a fluid path within the pump. Some preferred embodiments provide implantable infusion pumps with compliance positioned between an exit port of a pumping mechanism and an outlet (e.g. an opening in a catheter) of the infusion pump. Other embodiments provide compliance in fluid path in proximity to entrance port of the pumping mechanism. Insertion of compliance in a flow path that is down stream of the pumping mechanism may aid in minimizing negative effects associated with attempting to force fluid through a restricted flow path that is further down-stream, such as that offered by a catheter or other outlet component. Insertion of compliance before the pumping mechanism may aid in reducing negative effects associated with an up stream restricted flow path, such as that which might be offered by a rigid filter located between the reservoir and the pumping mechanism. Several structural components, assemblies, or configurations may be used as sources of compliance. For example, compressible structures (e.g. pillows, drums) are used within a aide port of the infusion pump. The compressible structures may quickly distort to accommodate for a large impulse of fluid into the flow path that cannot otherwise be readily dealt with. The compression, in turn, results in a restoring force being exerted that returns the structure substantially to its original volume so as to slowly force fluid from the flow path.

IPC: F27D17/00
Filed: 2001-04-06
Abstract: A regenerative furnace without flue gas circulation to the regenerator beds is heated by combusting synthesis gas with an oxidant. The synthesis gas is produced from steam and methane in a first regenerator bed, heated in the previous cycle while a second regenerator bed, cooled in the previous cycle, is heated by passing through it a hot flue gas from a source other than the furnace. Once the first regenerator bed is cooled through the endothermic chemical reaction of the steam and methane, it is heated by hot flue gas, while steam and methane are reacted in the second, now hot, bed thereby cooling it.
